CAR-MOVER.

Application filed June 24, 1915.

To all whom it may concern:

Be it known that I, CHARLES M. ROLPH, a citizen of the United States, residing at Monticello, in the county of Green and State of Wisconsin, have invented certain new and useful Improvements in Car-Mow ers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in car movers, and more particularly to that class of car movers in which a pinch bar is fulcrumedon a base plate that is adapted to engage the top of a rail, and the said fulcrumed bar is designed to engage the outer periphery of a car wheel and impart a, forward impulse to the car.

A further object of this invention is to provide a base plate in a device of this character which is adapted to be held tight upon the rail during the operation of the device.

A further object of the invention is to provide a device that is simple and durable in construction, inexpensive to manufacture, and one which will be very efficient in operation.

With these and numerous other objects in view, the invention consists of certain novel features of construction, combination, and arrangement of parts which will be hereinafter referred to and more particularly pointed out in the specification and claim.

In the accompanying drawings: Figure 1 is a side elevation of my improved car mover applied to use; Fig. 2 is a side elevation of the car mover applied to the top of a rail, showing the base plate in vertical section; Fig. 3 is a transverse vertical sectional view taken on the line 3-3 of Fig. 2; and Fig. 4 is a detail perspective view of my improved base plate and pinch bar spaced from one another.

In describing my invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which the numeral 1 designates the base plate of my improved device which comprises a substantially U-shaped member having side edges 2 and 3 which are adapted to straddle the top of a rail R as clearly shown in Fig.

Specification of Letters Patent.

3 .of the drawings. of the base plate 1 is formed a plurality of parallel rows of biting teeth 4 which are adapted to grip the top of the rail R. It will be noted that I have provided two of these parallel rows of teeth, so that they are adapted to engage the top or head of the rail R at the rounded portions of the same as clearly shown by the numeral 5.

The top of the base plate 1 has formed therein adjacent the rear end of the same a semi-cylindrical socket 6, and adjacent the front end of the same a forwardly inclined depression 7 for a purpose to be hereinafter more fully described. The forward end portion of the top of the base plate 1 slopes or is inclined forwardly as shown at 8, and has formed at the top of said inclined portion a shoulder 9 whereby a two-point contact with the periphery of the car wheel is had with this plate when the same is in position. The pinch bar or fulcrumed member of this device 10 has formed adjacent its forward end a cylindrical extension 11 having a circular bore 12 extending transversely therethrough. This cylindrical extension 10 is adapted to be positioned in the semi-cylindrical sockets 6 in the top of the base plate 1, and is adapted to be held therein by a U-shaped pivot pin 13 which extends through the bore 12 and has its arms 14 projecting downwardly through apertures 15 in the said base plate, that terminate in counter-sunk apertures 16 in the lower wall of said base plate. Nuts 17 are adapted to be positioned in said counter-sunk apertures 16 and to securely engage the ends of the arm sections 14 of the pivot pin 13. By this positioning, the pinch bar 10 will be fulcrumed with respect to the base plate 1.

The forward end 18 of the pinch bar 10 is adapted to be positioned in the inclined depression 7 in the top of the base plate 1 when the parts are assembled in normal position as clearly shown in Fig. 2 of the drawings. The upper face 19 of the forward portion 18 of the pinch bar is inclined so that the same may engage the outer periphery of the car wheel. This engagement between the outer face 19 and the outer periphery of the car wheel is made additionallv secure by the provision of a roughened surface 20 on the said outer face.

Disposed in the upper end of the pinch bar 10 is a socket 21 into which is adapted to be placed any desired form of operating On the inner surface 7 tion to the car wheel.

tool, for instance, an ordinary crowbar or any analogous implement.- The lengths of the operating tool 22 may be varied as desired to suit the user. this device are assembled as shown in Fig. 1 of the drawings, it will be noted thatthe base plate 1 is moved forwardly along the top of the rail R until it engages the outer periphery of the wheel W at its forward end, at two points; namely the forwardly inclined portion 8 of the same and the shoulder 9 formed thereon. By these two points of contact the base plate 1 will be firmly held beneath the said wheel, and the front end of the plate will be prevented from rising ofi the track or rail during the operation of the pinch bar 10. In other devices of this character where there was only a single point of contact between the base plate and the periphery of the car wheel, upon operation of the fulcrumed member of the device the forward end of the base plate, in the majority of cases, becomes lifted out of contact on the rail, thereby rendering the device insecure and liable to slide from its operative position.

The forwardly inclined depression 7 in the top ofthe base plate in my device forms a socket or shoulder in which the forward end 18-of the pinch member 10 is positioned while this device is being placed in posi- Also the particular pivotal construction involved in my device which is shown in Fig. 3 of the drawing and clearly described hereinbefore, is a very efficient means employed in a device of this character and one which will easily and efficiently perform the operation described.

The parallel rows of teeth 4 on the inner surface of the U-shaped base plate of my device, particularly the positioning of the rows '5 the purpose of which has been hereinbefore set forth, makes this device one that absolutely cannot become loose when once placed in operative position.

From the foregoing description of the Vhen the parts 'of' construction of my improved car mover, the manner of applying the same to use, and the operation thereof will be readily understood and it will be seen that I have provided a simple, inexpensive and eflicient means for carrying out the object of the invention.

I have particularly described the elements best adapted to perform the functions set forth, but it is obvious that various minor changes as to form, proportion, and in the minor details of construction may be resorted to within the scope of the appended claim without departing from. the spirit or sacrificingany of the principles of this invention.

'1 claim as my invention:

A car mover comprisingan inverted substantially U-shaped base plate, a plurality of teeth on the inner surface of the same, the top of said plate having a semi-cylindrical socket adjacent its rear end and a longitudinally extending forwardly inclined depression adjacent its forward end, the said forward end of the plate extending vertically downward and then inclined forwardly, a pinch bar having a cylindrical extension fulcrumed on the said socket, a U- shaped pivot pin extending laterally through said extension and having'its arms projecting downwardly through the top of said base plate, counter-sunk positioning meansto hold the ends of said arms, the forward end of the pinch bar positioned in the said inclined depression, and the outer forward face of said pinch ba'r being roughened for engagement with the outer periphery of the car wheel.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
